On Thursday, Friday, and Saturday, The Actor’s Summit will be performing “Photograph 51″, a play that tells the story of Rosalind Franklin, the scientist that took the x-ray diffraction Photograph 51 in 1952, the first picture to show the double helix structure of DNA. Her images and detailed calculations were used by James Watson and Frances Crick, without Franklin’s knowledge, to construct the first model of the double helix structure of DNA for which they won the Nobel Prize. Franklin’s contributions were never acknowledged by Watson or by Crick. The play focuses on the period 1951 through 1953 when Franklin was a researcher at King’s College, London.
